DESCRIPTION  
NC − No internal connection  
When read horizontally, Pin 1 is the bottom left pin.  
The SN65220 is a single transient voltage suppressor and  
the SN65240 and SN75240 are dual transient voltage  
suppressors designed to provide electrical noise transient  
protection to Universal Serial Bus (USB) 1.1 ports. Note  
that the input capacitance of the device makes it  
unsuitable for high-speed USB 2.0 applications.

Any cabled I/O can be subjected to electrical noise  
transients from various sources. These noise transients  
can cause damage to the USB transceiver and/or the USB  
ASIC if they are of sufficient magnitude and duration.  
GND  
USB ports are typically implemented in 3-V or 5-V digital  
CMOS with very limited ESD protection. The SN65220,  
SN65240, and SN75240 can significantly increase the  
port ESD protection level and reduce the risk of damage  
to the circuits of the USB port.  
CURRENT vs VOLTAGE  
7.5  
The IEC1000-4-2 ESD performance of the SN65220,  
SN65240, and SN75240 is measured at the system level.  
Therefore, system design impacts the results of these  
tests. A high compliance level may be attained with proper  
board design and layout.
